The invention is directed to bispecific molecules comprising an HIV-1 envelope targeting arm and an arm targeting an effector cell, compositions comprising these bispecific molecule and methods of use. In certain aspects, the bispecific molecules of the present invention can bind to two different targets or epitopes on two different cells within the first epitope is expressed on a different cell type than the second epitope, such that the bispecific molecules can bring the two cells together. In certain aspects, the bispecific molecules of the present invention can bind to two different cells, wherein the bispecific molecules comprises an arm with the binding specificity of A32, 7B2, CH27, CH28 or CH44.

Bispecific molecules comprising an HIV-1 envelope targeting arm

The present invention relates to bispecific molecules that are capable of localizing an immune effector cell that expresses an activating receptor to a virally infected cell, so as to thereby facilitate the killing of the virally infected cell. In a preferred embodiment, such localization is accomplished using bispecific molecules that are immunoreactive with an activating receptor of an immune effector cell and to an antigen expressed by a cell infected with a virus wherein the antigen is detectably present on the cell infected with the virus at a level that is greater than the level at which the antigen is detected on the virus by the bispecific molecules, and to the use of such bispecific molecules in the treatment of latent viral infections.
